Can't rename card to just-deleted card's name+issues

Deleted http://thefarmschool.wagn.org/Contact_Us and then tried to rename http://thefarmschool.wagn.org/Contact_Information to "Contact Information" and got a Wagn hitch (nothing on Airbrake). Tried to recreate it and discovered that Contact Information shows up from the Search bar, but going to it offers to add the card. Clearing the cache restores Contact Information, but doesn't help with the renaming.
